Why “Happy Science”?

Happy Science in Japanese is “Kofuku-no-Kagaku”. “Kofuku” means “Happiness”, and “Kagaku” means “Science”. In grammatically correct English, the translation would be “The Science of Happiness”. However, the “Happy Science” was adopted for simplicity, as it is easier to remember and can be pronounced by all the people around the world regardless of their country of origin or their level of English language. “Science” implies that we study the way to become happy.
